WOOD-SURFAGING MACHINE.
Specification of Letters Patent.
Patented Sept. 20, 1910.
Application filed. November 27, 1908. Serial No. 464,583.
To all whom it may concern:
Be it known that I, J OIIN WVARREN BELL, a citizen of the Dominion of Canada, residing at Vancouver, in the Province of British Columbia, Canada, have invented a new and useful Wood-Surfacing Machine, of which This involves a considerable amount of labor, or if the sand papering is done in a machine, if the wood is soft, as in the case of cedar, a wooly surface is thrown up which is objectionable on finished work.
In the machine which is the subject of this application the planed surface of the board is passed over or under a rapidly revolving highly polished roller which is applied to the surface of the wood with considerable pressure, and by virtue of the rapid friction of the highly polished surface and by the heat engendered by that friction, a hard finished surface is formed on the wood, the softer grain being filled with the resinous matter of the wood which resin is spread by the heat. If found necessary the planishing roll may be artificially heated and oil or wax may be applied either to the wood or to the planishing roll. The surface thus formed is not only highly polished, but being hard is less liable to injury.
The invention is particularly described in the following specification, reference being made to the drawings by which it is accompanied in which:
Figure 1, is a cross section through the rolls of the machine, showing the application of planishing rolls for finishing both sides of a planed board. Fig. 2, a side elevation of the same and Fig. 3, a plan with the oil vessel removed.
In these drawings 2 and 3 represent upper and lower planishing rolls between which the board 4 is fed, either from the delivery feed rolls of a planing machine, where forming part of the machine itself. The rolls 2 and 3 are highly polished and are retatable at a high rate of speed in bearing boxes 6 which are vertically movable in guides 7 in the side frames 8, of the machine; springs 9 being interposed between the bearing boxes and the ends of their guidesby which an adjustable pressure may be applied to press the rollers strongly on the surface of the board.
The planishing rolls 2 and 3 may be driven by any appropriate means preferably 111 opposite directions so that the friction of one is counterbalanced by that of the other, and to avoid dust or chips bein drawn in to the rolls the upper one should e driven in a direction opposite to that of the feed.
As drawn the planishing rolls are driven by a belt 10 passing over the pulleys 11 n the manner shown in Fig. 2 to drive them in opposite directions, a pivotally mounted tightening pulley 12 being applied to the slack side of the belt, which w1ll also 1ncrease the arc of the belt contact on the lower pulley 11..
A light openwork table extends between the side frames to support the board in its passage to and between the rollers.
\Vhere moldings require to be surfaced the periphery of the rollers both feed and polishing will obviously be formed to the outline of the molding, and means will be provided for supporting the moldlng to the rolls.
Melted wax, oil or other suitable dressing may be applied before it enters the rolls or to the rolls themselves which will not only serve to fill in the pores of the Wood and with the heat help to form a hard surface, but will lessen the friction of the rolls on the wood. This may be done in any suitable manner. In the drawing it is shown as applied by means of a fabric siphon 15 from a vessel 16 extending across the roll.
If found necessary the rolls may be artificially heated by the delivery of steam at 17 to the hollow of the rolls.
If one pair of rolls is not sufficient to attain the desired result in the matter of finish or hardness of surface a second or third pair may be added; but this is not material to the invention. as it is merely a multipllcation of the principal feature which consists n the combination with feed rolls of planishmg to the surface of the wood feed rolls between which the wood is passed,
rolls rotatable at a higher rate of speed in reservoir mounted adjacent to said roller the manner described and of the applicaand a capillary member carried by such res- 15 tion of oil or melted wax to the same. ervoir to wipe against said roller to apply an Having now particularly described my inunctuous material thereto, substantially as vention and the manner of its use I hereby shown and for the purposes described.
